Sensor Selection, Continued
If a sample is providing odd or unreliable test results with a certain sensor,
trying testing with one sensor smaller. This can sometimes provide more
reliable results.
Small samples can warm up very quickly with handling which may
interfere with testing results. If a sample is a different temperature than
the device, place both the sample and the device on the same counter
and let them come to room temperature for about 10 minutes before
testing again.
